Hi Allen, thanks for your response.
I will only be using what's in stack level 1 in my do until loop, adding 1 to it and comparing it to 50, so the construct would look like this:
DO 1 +
UNTIL stack level 1 > 50
the problem is, I don't know what nomenclature to use for stack level 1 so the calculator will recognize it...do I refer to it in the program as level 1, L1, LVL1, or what? I tried just leaving it blank, like this:
DO 1 +
UNTIL > 50
thinking it would default to stack level 1 and compare it to 50 in the absence any other specific variable, but that didn't seem to work.
I realize I could put level 1 into a variable and use that in the do until loop, but I was just hoping there was a way to directly use the contents of level 1 (or any other stack level, for that matter) in my do until loop.
Hope this clarifies my plight for you.
Thanks, and best regards, hal
P.S. Anybody out there know how to force a screen update during program execution without halting or pausing the program?
thanks again, hal
